Effects of Wavelength of Light Stimuli and Environmental Temperature on the Bio-Electric Potential and the Morphogenetic Properties of Pholiota nameko

Abstract

In this study, the relationship has been examined between the bio-electric potential and the morphogenetic properties of Pholiota nameko,for investigating the optimum farming conditions for mushrooms from engineering considerations. Initially, the eff ect of wavelength of light stimuli on the morphogenetic properties was investigated, based on the bio-electric potential under blue light was greater than under red light. The experimental results indicated that progressed morphogenesis obtained under blue light created large bio-electric potentials. This was followed by an investigation of the response characteristics of the bio-electric potential with respect to environmental temperature( from 14℃ to 22℃). This was then used to analyze the dependence of the morphogenetic properties. The experimental results indicated that a maximum response occurred,with correspondingly favorable morphogenesis obtained,at 14℃. Based on the above results, it is concluded that the value of the bio-electric potential is an eff ective measure for the objective evaluation of farming production.

Investigation of the Surrounding Environment′s Influence on Gait Sensing Using a Plant as a Sensor

“…However, the bioelectric potential of a plant is affected by the surrounding environment; for example, it varies with the concentration of formaldehyde in the air [5,6], air humidity, air temperature, and the soil moisture content [7]. Moreover, the bioelectric potentials of plants have been found to change with growing conditions, such as light levels and wind [8][9][10][11]. We anticipate that these properties can be exploited to produce a sensor and we are investigating measurement techniques that use plants.…”
